PACKING DEVICE FOR FOLDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 656,898, dated August 28, 1900. Application filed April 20, 1900- Serial No. 13,615. (No model.)

To ctZZ whom it may concern.

Beit known that I, HOWARD K. KING, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Packing Devices for Folding-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of

IO which- Figure 1, Sheet 1, is an elevation of part of a folding-machine having my invention applied thereto, onlysuch parts of the machine as are necessary to an understanding of my invention being shown. Fig. 2 is a front elevation of Fig. 1, the folding-rollers being in section and a part of the frame broken away. Fig. 3, Sheet 2, is a plan View, the foldingrollers and folding-blade being omitted.

This invention is designed to obviate a difficulty that has heretofore existed in the packing of sheets or signatures of paper of comparatively-large size in folding-machines, in that owing to lack of rigidity the sheets tended to collapse or fall over upon the return movement of the packing-trough plunger, in consequence of which the next sheet passing from the folding-rollers to be packed was liable to lodge against or back of one of 0 the adjacent previously-packed sheets, thus causing imperfect packing. I remedy this defect by providing a simple device for sup porting the packed sheets during the retraction of the plunger preparatory to packing the next-succeeding sheet coming from the folding-rollers in a mannerto render it impossible for such faulty packing to occur.

To this end the invention, stated in simple terms, consists in the combination, with the 0 usual packing-trough and reciprocative plun ger therein, of an oscillatory or reciprocatory arm adapted to impinge against and support the packed sheets or signatures during the retraction of the plunger and to move out of the way on the return movement of the plunger to pack the succeeding sheet in such manner as not to obstruct the packing of said sheet.

, The invention consists, further, in certain features and combinations of mechanism hereinafter described, of which the said oscil latory or reciprocatory arm is anelement.

In the particular construction of the invention shown in the accompanying drawings,

forming a part ofthis specification, the plunger is adapted to pack both ways-that is, on each side of the line upon which the sheets fall into the packing-trough; but it will be quite obvious that theimprovement is equally applicable when the packing is to be done on one side or direction only.

Referring to the said drawings, 1 represents the usual folding-rollers between which the sheets are tucked by the folding-blade 2, Fig.

2, and pass down to the packing-trough 3.

represents rollers similar to rollers 1, between which the sheet passes before reaching the trough; but these latter rollers may be dispensed with.

5 is the plunger, which is adapted to recip- 7o rocate within the packing-trough by any wellknown suitable means-in the present instance by means as follows: 6 is a strap-eccentric on a shaft 7, having on its end a spurgear 8, with which is engaged a pinion 9 on a'shaft 10, that is driven from the main source of power by a belt passing over a pulley 11. The rod 6 of the eccentric-strap is pivotally connected to the free end of an arm 12, that extends from a vertical shaft 13, which is jour- 8o naled in bearings of the frame F of the machine. A rod 14L has one endpivoted on a vertical shaft 15, that is eccentric to shaft 13,

it being supported in arms 16, projectingfrom said shaft. The other end of said rod is pivoted to a crank-arm 17 of a rotatable sleeve 18, that is mounted on a post or hearing 19, which is supported by the frame of the machine. A second crank-arm 20 on said sleeve is pivotally connected to the rod 5 of the plunger 5.

The above-described mechanism for actu ating the plunger is not new;

Secured to the shaft 13 is an arm 21, whose free end projects over the top of the'packingtrough. It will be seen that when the said shaft is oscillated this arm and the plunger will be caused to move simultaneously in opposite directions and past each other.

Having thus described the construction. of roe my invention, I shall now explain the mode of operation thereof as follows: Assuming the parts to be in the positions shown in the drawings, in which the plunger and the arm 21 are at the limit of their movement in one direction, when, as seen in Figs. 2 and 3, the plunger is against the body of the packed sheets 1) on the right in Fig. 2 and the said arm is against the upper part of the pack 19 on the left, the lower edges of the pack being supported by the usual yielding catches or flappers 22, now as the cam-shaft 7 continues its rotation, thus oscillating the shaft 13, (the sheet to be packed having fallen into the packing-trough between the plunger and arm,) the plunger will be caused to advance toward the sheet and finally carry it up against the pack 1). Simultaneously it is manifest the arm 21 will move in the opposite direction, its end striking against and bend ing over the top of the sheet and passing the latter as it is being carried by the plunger, until it (the said arm) impinges against, and thus supports the pack 19, at which time the plunger and arm have exchanged positions. These operations are repeated with the entrance of each sheet into the packingtrough. It will of course be understood that the usual cam (marked 23 in the drawings) that governs the vibrations of the folding-blade 2, and the eccentric 6, that governs the oscillations of the shaft 13, and consequently the movements of the plunger and arm 21, shall be suitably timed or related, so that said plunger and arm shall reciprocate immediately after the descent of the sheet into the packingtrough.

I may remark that while I have shown and described in the d rawings devices for effecting vertical adjustments of the packing-trough, these devices do not form any part of my present invention and are not new. I have therefore deemed it unnecessary to particularly describe the same.

While I have shown and described but one (and that which I consider the best) form of my improvement it will be obvious to any one skilled in the art to which the invention reclaim as new and desire to secure by Letters Patent- 1. In a sheet-packing device, the combination of the packing-trough, the reciprocatory plunger therein, the oscillatory arm, means for actuating said arm substantially simultaneously with the movement of the plunger, but in the opposite direction, substantially as and forthe purpose set forth.

2, The combination of the folding devices, the packing-trough, the plunger therein, the oscillatory arm, said arm and plunger being arranged with relation to each other and the said folding devices substantially as shown, means for actuating the plunger to pack the sheets alternately in opposite directions, and means for actuating said arms correspondingly with the movement of the plunger, but in opposite directions, substantially as and for the purpose set forth.

3. In a sheet-packing device, the combination of the packing-trough, the reciprocatin g plunger therein, a movable arm or the like, extending above the latter, means for causing said arm to impinge against and support the pack of sheets when the plunger is retracted therefrom, and for carrying said arm out of the path of the sheet to be packed on the forward reciprocation of the plunger, substantially as set forth.

,4. In a sheet-packing device, the combination of the packing-trough, the reciprocating plunger therein, the oscillatory arm, and means for actuating said arm and plunger simultaneously in parallel horizontal planes and in opposite directions, substantially as and for the purpose set forth.

In testimony whereof I have hereunto affixed my signature this (3th day of April, A. D.
